It includes the discovery of resinous substances. Derivatives of phenol and formaldehyde that are suitable for use in phenol/formaldehyde resins are discussed extensively in this chapter. This chapter summarizes the applications, uses, and properties of the monomers of phenol and formaldehyde. Special ...

Phenol-formaldehyde condensation products are one of the lowest cost adhesives for structural purposes. Thecondensation reactioncan be carried out under basic or acidic conditions. The former case leads to ‘resols’, while acidic condensation produces ‘novolacs’, shown in (11) and (12), respect...
Resol type phenol resins containing scarcely or no phenol mononucleus compounds (monomers) and phenol dinuclei compounds (dimers) and their methylolated derivatives and scarcely containing molecules having an apparent molecular weight of more than 2500 are produced by reacting phenol with formaldehyde in...
